EDMUND E. EGGLESTON, OF WICHITA, KANSAS.

BICYCLE-LOCK.

To all whom it may concern:

Be it known that I, EDMUND E. EccLns- TON, a citizen of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Bicycle- Locks, of which the following is a specifi cation.

My invention relates to an improvement in bicycle locks, and the object is to provide a device which may be applied to one of the standards of the machine at a point where it is out of the way, and at the same time may be conveniently brought into play to lock the wheel when desired without the use of a key, and which will require a key especially provided for it to unlock the machine.

A further object is to provide a lock which cannot be easily taken apart or picked.

WVith these objects in view, my invention consists in a locking member having a bolt attached thereto, the locking member inclosing the locking mechanism, and a lock case made in two sections and secured to the frame of the machine, and the bolt adapted to be swung between the spokes of the wheel, whereupon the locking mechanism automatically secures the bolt in place until the key designed to unlock it is used in the lock.

My invention further consists in certain novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claims.

In the accompanying drawings :-Figure 1 shows a portion of a bicycle with my improved lock in position on the right rear standard; Fig. '2 shows the internal construction of the lock, case being removed; Fig. 3 is a side elevation looking from beneath; Fig. & is a perspective View of the top half of the lock case; Fig. 5 is a similar View of the lower half or section of the same; and Fig. 6 is an illustration of one of the screws preferably used to secure the two halves of the lock case together.

This lock is adapted to be permanently attached to the frame of the bicycle, and when the bolt is in the position shown in Fig. 1, the wheel is unlocked. This bolt 1 is at tached to member 2, which latter member rotates within the casing of the lock. The casing is made of two parts, as illustrated in Figs. 1 and 5. Within the member are the pawls 3 and 1. One end of each pawl is designed to enter notches contained in memthe top portion of the Specification of Letters Patent.

her 2. These pawls are forced into the notches by springs 5 and 6. These pawls 3 and 4: have projections 7 and 8 respectively with which the wings of the key 9 engage to force the pawls out of the notches, thus leaving member 2 free to rotate.

To look a bicycle, the member or bolt 1 is turned so as to extend between the spokes of the wheel 10. The pawls 3 and a now engage the notches where tiey remain until the key 9 is inserted and rotated. It will be noted that member 2 contains a double set of notches. This is to lock the bolt out of the wheel as well as in the wheel, to avoid accident while running on the road. It will be seen that one side of each of the notches used to lock the bolt out of the wheel is beveled so that the proper amount of force will force the bolt between the wheel spokes without using the key, thus saving time.

The lock is put on the wheel frame as. follows: The countersunk screws 11 and 12 are passed through holes in the lower case member and screwed into clamp 13. The top portion of the case is now put in position, and screws having, in addition to a countersunk head, a square projection, are passed through top portion of case and screwed in lower portion. The square projection is now cut away, leaving the top of case smooth. This method of attaching makes it very di'Hicult to remove the look from the bicycle frame.

It is evident that more or less slight changes might be resorted to in the form and arrangement of the several parts described, without departing from the spirit and scope of my invention, and hence, I do not wish to limit myself to the exact construction herein set forth, but

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A look comprising a case made in sections, spring-actuated pawls pivotally connected thereto, a bolt, and a locking member connected to the bolt and rotatably supported within the case and provided with two varieties of internal notches adapted to be automatically engaged by the pawls, one variety of notches being adapted to co-act with the pawls to lock the bolt in position, and the other variety of notches being constructed each with an inclined wall, whereby when said notches are engaged by the pawls, the bolt will be yieldingly held in position.

2. A lock comprising a case having an upper and lower section, a clamp connected to the lower section, means connecting the two sections together, spring-actuated pawls pivotally mounted within the case, a bolt, and a locking member connected to the bolt, and rotatably supported within the case and provided with two varieties of internal notches adapted to be automatically engaged by the pawls, one variety of notches being adapted to co-act with the pawls to lock the bolt in position, and the other variety of notches being constructed with an inclined wall, whereby when said notches are engaged by the pawls, the bolt will be yieldingly' held in position.

In testimony whereof I affix my signature, in the presence of two witnesses.
